Relationship between pre-extubation positive end-expiratory pressure and oxygenation after coronary artery bypass grafting

Abstract

IntroductionAfter removal of endotracheal tube and artificial ventilation, ventilatory support should be continued, offering oxygen supply to ensure an arterial oxygen saturation close to physiological.ObjectiveThe aim of this study was to investigate the effects of positive-end expiratory pressure before extubation on the oxygenation indices of patients undergoing coronary artery bypass grafting.MethodsA randomized clinical trial with seventy-eight patients undergoing coronary artery bypass grafting divided i…
